Kenwood TH-D74 | The SWLing Post

Many thanks to SWLing Post contributor, TC, who shares the following response to Ivan’s post about the Kenwood TH-D74 on mediumwave:

A couple of years ago, I published a side-by-side comparison of the TH-F6A and the TH-D74 on YouTube comparing reception of a local AM broadcast station. The F6A was far more sensitive on the AM broadcast band than the TH-D74.

I didn’t take the internal orientation of the bars into account, but the D74 is less sensitive in pretty much any orientation compared to the older F6A.

I contacted Kenwood about the difference, and they stated something to the effect of while the TH-D74 does receive MW, it wasn’t necessarily designed for it, and thus the reception there suffers compared to the F6A.

However, the tradeoff here seems to be better shortwave reception in the TH-D74 compared to the F6A. Hook the D74 up to a large wire antenna and you can easily pull in stuff on the shortwave broadcast and ham bands, and the IF filters help quite a bit as well.

Thanks for sharing, TC! I own a few wideband handheld transceivers so I keep a short SMA “pigtail” in my EDC pack that I can use to enhance HF performance. I simply clip a 15′ wire onto the pigtail’s exposed conductor to enhance HF performance. Also, as Ivan points out, inductively pairing any of these tiny radios with a mag loop antenna will also augment performance on mediumwave.

Thanks again for sharing!

Many thanks to SWLing Post contributor, Ivan (NO2CW), who writes:

One category of receivers not much talked about are the wideband handhelds. I first owned one of those in 1992 when I paid a ton of money for an AOR-1000. Not only did it cost me a lot but I also ordered it from the UK so it was not subject to the “cellular blocked” rule. Don’t ask me why, it never made any difference in the end.

As a busy shortwave listener at the time I was eager to check out reception as the radio also featured Shorwave coverage and even a BFO (Beat Frequency Oscillator) knob! To sum it up it was a great receiver above 30 mHz but Shortwave and Mediumwave was barely there, with a 15 kHz wide filter and low sensitivity.

Well today I have in my hands a Kenwood TH-D74A – a top of the line handheld triband amateur radio transceiver with Medium Wave and Short Wave coverage. The radio is expensive due to the presence of GPS, D Star and APRS, but those are a features for the radio amateur. What about performance on the low frequencies?

Here is my video of the test which revealed surprising results:

So next time you consider purchasing a new receiver,as you dive into the choice of portables, SDRs, tabletops and classics from eBay you may consider adding this category as well – handhelds with wide band coverage.

Thank you, Ivan! You’ve inspired me to check out mediumwave performance on a few wideband handy talkies I own: the Yaesu VX-3R, Yaesu FT2DR and the Kenwood TH-F6A. To my knowledge, all three have internal ferrite bars (tiny ones) but I’ve never actually compared their performance with each other. That could be a lot of fun. I also own an AN200 MW loop antenna so this could be an excellent test to see how it pairs with each radio. I’m especially curious about the wee VX-3R!

Thanks again, Ivan. We always enjoy your videos and posts.
